WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd. WebC = 2*π*RC = 2*π*14C = 87.9646 cm. Therefore, the circumference for this example is 87.9646 cm. Apart from the circumference, having the value of the radius also allows you to find the area of the circle. This time, you use a different formula:
Calculate the diameter from circumference - YouTube
WebHence, the diameter is 49cm. Example 2: Calculate the diameter of a bicycle wheel if its C is 2155 mm. d = C ÷ π = 2155 ÷ 3.142. Therefore, the circumference of the wheel is 685.87 mm. Example 3: Suppose a merry … WebJan 16, 2024 · Getting diameter from circumference Since we know circumference and diameter are related by \pi π, we can use \pi π to find diameter if we know circumference.

The equation for circumference of a circle is: c=\pi d c = πd. If written instead in terms of the radius, the circumference calculation is instead: c = 2 \pi r c = 2πr. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) WebDiameter = Circumference ÷ π. Diameter of a Circle Using Radius. ... If the radius of a circle is given in 'r' units then it is easy to determine the diameter of the circle formula.
